The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a "whole genome shotgun" approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in china and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2214.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.29% of the rice genome with an average base accuracy of higher than 99%. The coverage of the draft sequence, the randomness of the sequence distribution, and the consistency of BIG-ASSEM-BLER, a custom-designed software package

A total of 719 expressed sequence tags （EST） clustered into 329 non-redundant EST groups are obtained from the sporophyte cDNA library of red algae, Porphyra yezoensis. Gene Ontology （GO） analysis is employed in characterizing 60 strictest annotated unique genes out of the 329 EST groups and some domains such as COX1, SodFeC, GST-N, SHMT, and RNase-PH related to the enzymes and proteins functioning in cells have been identified by HMMPFAM search. As its leafy gametophyte, the similar codon usage with strong bias is found in P. yezoensis filamentous sporophyte, regardless of some differences found in given amino acids. The average GC content of the 329 unique genes is 53. 0 % . In contrast, the third nucleotide of codon exhibits a higher GC content （ 72 % ） than that of the first （58%） and the second （42%） nucleotides. Similarity search of the present study shows a novel EST ratio of 60.2%, which is against the Porphyra ESTs database, suggesting further investigations towards elucidating the characteristics of Porphyra functional genome.

Expressed sequence tags (ESTs) are widely used in gene survey research these years. The EST Pipeline System, software developed by hangzhou genomics institute (HGI), can automatically analyze different scalar EST sequences by suitable methods. All the analysis reports, including those of vector masking, sequence assembly, gene annotation, Gene Ontology classification, and some other analyses, can be browsed and searched as well as downloaded in the Excel format from the web interface, saving research efforts from routine data processing for biological rules embedded in the data.

中国蛋白质组学第二届学术大会

作者： Jun Wang, JianGuo Zhang, SiQi Liu, Jian Wang, HuanMing Yang, Jun Yu, Gane Ka-Shu Wong (Beijing institute of genomics, Chinese Academy of Sciences, Beijing 101300, china James D. Watson institute of zhejiang university, hangzhou genomics institute, key laboratory of bioinformatics of zhejiang province, hangzhou 310007, china)

We are releasing an integrated suite of genomic data for indica rice, including a sequence with essentially complete non-fragmented coverage of the genes, and confirmation for the genes through EST, SAGE, and proteomics. Comparisons with japonica rice indicate that differences in gene content between the subspecies are at most a few percent. In contrast, almost half the rice genes have no homolog (NH) in Arabidopsis, and these are confirmed even in proteomics. We argue that these so-called orphan genes are the by-products of an ongoing process of evolution by gene duplication. Although some orphan genes are likely to be dead, many others are evolving lineage-specific functions.

Computational Identification of Protein-Protein Interactions in Rice Based on the Predicted Rice Interactome Network

引用

genomics,Proteomics & bioinformatics 2011年第Z2期 128-137页

作者： Pengcheng Zhu1, Haibin Gu1, Yinming Jiao1, Donglin Huang1,2, and Ming Chen1,2,3 1Department of bioinformatics, College of Life Sciences, zhejiang university, hangzhou 310058, china 2James D. Watson institute of Genome Sciences, zhejiang university, hangzhou 310058, china 3State key laboratory of Plant Physiology and Biochemistry, College of Life Sciences, zhejiang university, hangzhou 310058, china

Plant protein-protein interaction networks have not been identified by large-scale experiments. In order to better understand the protein interactions in rice, the Predicted Rice Interactome Network (PRIN; http://***/ prin/) presented 76,585 predicted interactions involving 5,049 rice proteins. After mapping genomic features of rice (GO annotation, subcellular localization prediction, and gene expression), we found that a well-annotated and biologically significant network is rich enough to capture many significant functional linkages within higher-order biological systems, such as pathways and biological processes. Furthermore, we took MADS-box do- main-containing proteins and circadian rhythm signaling pathways as examples to demonstrate that functional protein complexes and biological pathways could be effectively expanded in our predicted network. The expanded molecular network in PRIN has considerably improved the capability of these analyses to integrate existing knowledge and provide novel insights into the function and coordination of genes and gene networks.

Extremely Low Frequency Magnetic Fields (ELF MF) has been considered as a “possible human carcinogen” by International Agency for Research on Cancer (IARC) while credible mechanisms of its carcinogenicity remain unknown. In this study, a proteomics approach was employed to investigate the changes of protein expression profile induced by ELF MF in human breast cancer cell line MCF7, in order to determine ELF MF-responsive proteins. MCF7 cells were exposed to 50 Hz, 0.4 mT ELF MF for 24 h and the changes of protein profile were examined using two dimensional electrophoresis. Up to 6 spots have been statistically signifi-cantly altered (their expression levels were changed at least 5 fold up or down) compared with sham-exposed group. 19 ones were only detected in exposure group while 19 ones were missing. Three proteins were identified by LC-IT Tandem MS as RNA binding protein regulatory subunit、Proteasome subunit beta type 7 precursor and Translationally Controlled Tumor Protein. Our finding showed that 50 Hz, 0.4 mT ELF MF alternates the protein profile of MCF7 cell and may affect many physiological functions of normal cell and 2-DE coupled with MS is a promising ap-proach to elucidating cellular effects of electromagnetic fields.
